hive 不同用户 权限设置 出错处理

今天安装了hive

在a账号安装的，一切正常

但是到其他账户下，报错

>show tables;

Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

以为是权限问题

查看log

Nested Throwables StackTrace:
org.apache.commons.dbcp.SQLNestedException: Cannot get a connection, pool error Could not create a validated object, cause: A read-only user or a user in a read-only database is not permitted to disable read-only mode on a connection.

后来的解决方案:一个老外的方案:

I had the same issue and resolved it by the following way. The issue is because of two possible reasons. Either, the user you logged in as (do 'whoami' ) does not havewrite access to the derby metastore database directory used by Hive.So, go to /var/lib/hive/metastore/metastore_db (this is the defaultin most cases) and verify if your user id has permissions by doing anls. In case your userid does not have permissions, you should ask the owner of the directory to grant write permissions to you. So,login as the owner/the super user and execute cd /var/lib/hive/metastore/metastore_db chmod a+rwx . --recursive Be warned that this will give permissions to all users. Tweak r-w-x bits accordingly though. The other possible reason is that derby is a single user database. So, please clear the lock files by going to cd /var/lib/hive/metastore/metastore_db rm *.lck
